SHUTTLE FOR LOOMS.

Specification of Letters Patent.

Patented Sept. 10,1912.

Application led November 26, 1909, Serial No. 530,067. Renewed February20, 1912. Serial No. 678,957.

To all whom it may concern:

Be it known that we, ADoLPH VVIDMER and SAMUEL VIDMER, citizens of theUnited States, residing in Paterson, Passaic county, New Jersey, haveinvented a certain new and useful Improvement in Shuttles for Looms: andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, `such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention relates to loom shuttles and particularly to the meansfor supporting In one class of such shuttles, notably for narrow-warelooms, the quill is arranged on an axial support which is secured in theshuttle at both ends and is rotatable on its support so as to dischargethe thread; usually this support takes the form of a pin which lits intoa hole in the shuttle at one end and is suitably held at the other, andas the pin is bodily removable from the shuttle it is often lost andbesides makes necessary some experience and skill in the assembling anddisassembling of the parts.

Our object in the present invention 1s to provide a shuttle in which theaxial support for the quill remains at all times attached to the shuttlebody.

A further object is so to arrange and construct the parts that when theshuttle is in use the axial support for the quill will remain positivelyin proper position and not be likely, for instance, to becomesuiiiciently displaced so as to project and possibly cause damage to thegoods being woven.

To this end our invention consists in providing in one of two opposedwalls in a shuttle body, as in the bow thereof, a recess entering saidwall from one side thereof and opening toward the other wall, togetherwith an axial support for a quill, which support projects from the otherof said walls and has its free end normally engaged in, but movablelaterally of the axis of said sup port out of, said recess.

Referring to the accompanying drawing, in which the invention is fullyshown, Fig- Aure l is a front elevation of the improved supportingmeans; Fig. 2 is a horizontal sectional viewfon line -m of Fig. l; Fig.3 is a vertical sectional view on line g/- 1/ of Fig. l, loo-king towardthe left; Fig. 4 is a similar view on line 5 2, looking toward theright; and, Fig. 5 illustrates a detail.

a designates the shuttle body, the same having the usual bow o and awire guard c to keep they quill from engaging the shed.

d is the lquill and e the usual tension-device adapted to bearfrictionally against the quill, operating as a brake thereon.

The axial support for the quill is constructed and the manner ofmounting it is as follows: f is a pin or spindle, formed, say, of wire,being straight throughout, except at one end, which is turned olfsubstantially at right angles, as at g. This pin forms the said axialsupport and onto it the quill may Vbe placed, as shown in Fig. l, so asto rotate freely.

The two opposed walls la. of the shuttlebody support the pin in theusual position, z'. e., parallel with the base of the shuttlebody andare constructed for that purpose as follows: The wall 7L has anelongated recess or groove z' extending perpendicular to the base of theshuttle-body. Over this groove is secured, as by screws j, one arm of anangle-plate 7c, the other arm of which is secured in like manner againstthe face of the base of the shuttle-body which is within the bow. At theend of the groove which is the farther from the base the plate is formedwith a hole Z. Before securing the plate in position the end g of thepin is passed through this hole, whose diameter is slightly larger thanthe cross-section of the pin. the plate and groove form a bearing forthe part g of the pin, in which said part g fits rather snugly; the pinmay then be moved in the bearing from a position in which it lies in thelongitudinal axis of the shuttle, as indicated by the dot-and-dash linesin Fig. 2, to the position indicated by full lines in the same ligure.When moved onl the party as an axis the body portion of the pin willfollow a plane which is perpendicular to said axis, unless pressure isapplied in the direction of the length of said axis, as toward the baseof the shuttle, the in being somewhat elastic so that it will yield tosuch pressure but return to its normal disposition when the pressure isremoved.

When the plate is then secured,

Entering the wall 7L from one side thereof and open toward the wall z isa recess or groove m. The ent-rance end of this recess or groove issomewhat out of the plane in which the body portion of the pin f tends ithe quill is slipped onto t-he same. The pin,

carrying the quill, is then turned on its axis g toward the positionindicated by dot-anddash lines in F ig. 2 its free end being pressedtoward the base of the shuttle until it enters and finally seats at theclosed end of the recess m. In this position it will be held by virtueof its elasticity, unt-il, when the quill is to be removed, pressure isagain applied to clear its free end from the recess.

lNe do not wish to be limited to the details of construction hereinshown and described, whatwe claim being: 'The combination of a shuttlebody having opposedwalls and a recess in one of said walls entering thesame from one side thereof and open toward the other wall, and anelastic pin having a substantially straight body-portion and one endturned oii' at an angle to said body-portion and journaled in the otherwall, whereby said pin may swing on said turned-oft end thereof as apivot, the free end of said body-portion of the pin being engageable insaid recess and the entrance end of said recess being disposed fartherthan the other end of said recess from the plane in which thebody-portion of the pin swings when the latter is clear of the recess,substantially as described.

In testimony, that we claim the foregoing, we have hereunto set ourhands, this 23rd day of November, 1909.
